SynctoneBinaural Beats
A calmer mind. A brighter you.
Binaural beats for sleep, focus, and calm - pick a preset or dial in your own frequency, add background noise, set a timer, and control it all from your lock screen.
What are binaural beats?
Play two slightly different tones, one in each ear, and your brain perceives a third, pulsing “beat” as the difference between them. A 200Hz tone in one ear and a 210Hz tone in the other creates a perceived 10Hz beat. Listening to that beat is thought to gently guide your brain toward calmer or more alert states, depending on the frequency - best experienced with stereo headphones.
